Now put the photo across the middle of the candle. Over it put a sheet of wax paper while making sure there are not any air bubbles that exist under the paper.
Get your hairdryer, or the hot air gun. Turn it on and point it at the area of the photo. The upper layer of candle wax is going to start melting together with the tissue paper. The picture should get darker.
Once the picture gets a coloration which is consistent, then you will want to slowly pull the wax paper off. Leave the candle alone to set for half and hour.
Your gift is done!
